today I aquascaped the 34 l tank, gave it new life after Hump and Hep moved out. Cleaned everything out and "redesigned" it with dark gravel, rocks, plenty of plants. Conditioned the water, adjusted the pH.Now it is cycling.

My fingers are wrinkled and I almost grew swimming skins in between my fingers.

Right! An important question, did you think about stocking density in your tank after adding all these fish?With smaller tropical fish you should ALWAYS calculate 2 liters of water per 1 cm of grown fish length. It's different with shoaling fish though since they're usually smaller, so with the tetras you could count 1 liter per 1cm fish length. So check the "maximum" length of every fish you're intending to keep there, and check if they'll all fit!

Thanks Nossie, I'll check it out for sure I don't want this to happen again. Only now roughly calculated it should be fine without pushing, but I'll have a more exact calculation.Geez I'm so glad to have you guys on here with all those good tips and advices. You are so great!

LOL, Andiy, yeah why not, it is such fun... but I won't be able to tell them apart ... my hubby said what about Itsy, Bisty, Teeny, Weeny... etc.... just thinking all other fish in our home do have names and the "poor" Tetras shouldn't... I just love it sometimes to be a bit crazy... LOL
